Description

Technical Field

[0001] The present invention relates to the technical field of smart home, and specifically to a smart home gateway. Background Art

[0002] With the development of network technology and modern communication technology, the intelligentization of household devices has become a trend of household modernization. At present, a smart home gateway can realize the interconnection between internal terminals of a home network and communication with an external network to meet the needs of people for living, working, entertaining and communicating at home.

[0003] One side of the smart gateway usually has multiple slots for inserting power cords. In the actual use process, multiple power cords usually need to be inserted into the slots to ensure the data transmission of the smart gateway to other network devices in the home. In the daily use of this connection area, the current flows relatively frequently, so the temperature is usually higher than that of the gateway body. Coupled with the common installation environment, the connection area between the slot and the power cord is exposed and is easily attached by dust in the air. Poor contact may occur during long-term use, resulting in a temperature rise, and further may lead to potential safety hazards.

[0004] Therefore, the present invention proposes a smart home gateway. Summary of the Invention

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figure 1-11 , the present invention provides a technical solution: a smart home gateway, including:

[0033] Embodiment 1,

[0034] A housing 1, inside which there is an integrated component 2 for network transmission of various external devices, fixed to the bottom of the inner wall of the housing 1. On one side of the housing 1, there are a plurality of slots 3 for inserting a power cord. The above are prior arts, so no further description will be given;

[0035] In this solution, above the integrated component 2, there are a plurality of fins 4 and they are fixedly connected to it. The fins 4 pass through the housing 1 and are fixedly connected to it. The fins 4 are made of a metal material with strong heat dissipation performance. During the daily use of the gateway at normal temperature, the internal integrated component 2 can dissipate heat through the fins 4;

[0036] The wall of the housing 1 is provided with a first ventilation groove 5 and a second ventilation groove 6. The first ventilation groove 5 and the second ventilation groove 6 are diagonally distributed. This distribution setting is to maximize the flow area of the air body inside the housing 1 when the air body enters the housing 1 from the first ventilation groove 5 and then exits from the second ventilation groove 6, thereby improving the cooling effect of the integrated component 2 inside the housing 1;

[0037] The outer wall of the housing 1 is provided with a bottom box 7 for supporting the power cord. One side of the bottom box 7 is fixedly connected to the housing 1. An upper box 8 is provided above the bottom box 7. The bottom box 7 and the upper box 8 are slidably connected by a bolt. During installation, the upper box 8 can be pulled out from above the bottom box 7, and then the power cord is docked with the slots 3 one by one. Then the upper box 8 is covered above the bottom box 7. A pad 42 is provided at the bottom of the bottom box 7 and is fixedly connected thereto. The pad 42 has adhesiveness. When the gateway is placed on the desktop, the adhesiveness of the pad 42 can make the placement of the housing 1 more stable. The bottom box 7 and the upper box 8 are combined to block the port area of the slots 3, thereby reducing the entry of dust into the interface and reducing the occurrence of poor contact. A plurality of air outlet pipes 9 are provided on one side of the housing 1 and are all fixedly connected thereto. An air box 10 communicated with the air outlet pipes 9 is provided on the inner wall of the housing 1. One side of the air box 10 is fixedly connected to the inner wall of the housing 1. A cooling unit 11 for sending air into the air box 10 is provided inside the housing 1. The air body generated by the cooling unit 11 acts on the connection area between the slots 3 and the power cord through the air outlet pipes 9 and is discharged from the gap between the upper box 8 and the lower box, providing good ventilation and cooling for this area and reducing the occurrence of potential problems caused by high temperature;

[0038] The cooling unit 11 includes a motor 20 located inside the integrated component 2. The outer wall of the motor 20 is fixedly connected to the integrated component 2. A temperature sensor 41 is provided inside the housing 1 and is fixedly connected thereto. The temperature sensor 41 is electrically connected to the motor 20. A connecting shaft 21 is provided at the end of the motor 20. The connecting shaft 21 is connected to the rotating shaft of the motor 20 through a coupling. A first bevel gear 22 is provided on the outer wall of the connecting shaft 21 and is fixedly connected thereto. A second bevel gear 23 meshing with the first bevel gear 22 is provided on one side of the first bevel gear 22. A first shaft body 24 is provided inside the second bevel gear 23 and is fixedly connected thereto. The first shaft body 24 is rotatably connected to the housing 1 through a fixing block. One side of the fixing block is fixedly connected to the housing 1. A belt 25 is provided on the outer wall of the first shaft body 24. A second shaft body 26 is provided inside the belt 25. The belt 25 drives the first shaft body 24 and the second shaft body 26 to rotate simultaneously. A fan blade 27 is provided on the outer wall of the second shaft body 26 and is fixedly connected thereto. The end of the second shaft body 26 is rotatably connected to the integrated component 2. An air cylinder 28 is provided outside the fan blade 27. The bottom of the air cylinder 28 is fixedly connected to the housing 1. The air cylinder 28 is located on one side of the first ventilation groove 5. A connecting pipe 29 is provided above the air cylinder 28 and is communicated therewith. The connecting pipe 29 has an air outlet effect above the air cylinder 28. The other end of the connecting pipe 29 is fixedly connected to and communicated with the air box 10;

[0039] When the temperature sensor 41 senses that the temperature inside the housing 1 is too high, it will send a start signal to the motor 20, causing the motor 20 to drive the connecting shaft 21 and the first bevel gear 22 for transmission. Then, the first bevel gear 22 meshes with the second bevel gear 23, driving the belt 25 on the outer wall of the first shaft body 24 and the second shaft body 26 for transmission, so that the second shaft body 26 drives the fan blade 27 on its outer wall to rotate. Since the air inlet position of the air duct 28 is aligned with the first ventilation slot 5, the rotating fan blade 27 can suck in external air, send it into the interior of the first air box 10 through the connecting pipe 29, and then discharge it from the multiple air outlet pipes 9. Since the multiple air outlet pipes 9 correspond one by one to the insertion positions of the multiple power cords, the sent air body can perform synchronous air-cooling on the port areas of the multiple slots 3, ensuring good ventilation in the connection area, keeping the connection temperature within the applicable range, and reducing unnecessary potential hazards.

[0040] According to the above embodiment, Embodiment 2,

[0041] The inner wall of the housing 1 is provided with a first baffle 12 and a second baffle 13. Both the first baffle 12 and the second baffle 13 are slidably connected to the housing 1. The first baffle 12 and the second baffle 13 respectively block the first ventilation slot 5 and the second ventilation slot 6. A ventilation unit 14 for driving the first baffle 12 and the second baffle 13 to translate in opposite directions simultaneously is provided inside the housing 1. Through the ventilation unit 14, when the temperature of the gateway is too high, external air can be automatically circulated inside the housing 1, thereby reducing the temperature of the overall integrated component 2 and further ensuring that the device has a stable transmission effect;

[0042] The ventilation unit 14 includes a second air box 30 located on one side of the air duct 28. The second air box 30 is connected to the air outlet hole of the air duct 28. The port part of the second air box 30 covers the interval areas of the multiple fins 4, which enables the air body entering the second air box 30 to simultaneously dissipate heat from both the integrated component 2 and the fins 4, making the heat dissipation effect of the gateway better. A first wire 31 is provided at the end of the first baffle 12 and fixedly connected thereto. A second wire 32 is provided at the end of the second baffle 13 and fixedly connected thereto. Springs 33 are provided outside the first wire 31 and the second wire 32. Fixing clips 34 are provided at the ends of the springs 33. There are two springs 33 and they are exactly equal. One end of each spring 33 is fixedly connected to the first wire 31 and the fixing clip 34 respectively, and the other end of the other spring 33 is fixedly connected to the second wire 32 and the fixing clip 34 respectively. There are multiple fixing clips 34 inside the housing 1, all fixedly connected to the housing 1 and used for supporting the first wire 31 and the second wire 32. The first wire 31 and the second wire 32 both pass through the fixing clips 34 and slide relative to them;

[0043] In the normal state, the elastic force of the spring 33 pushes the first baffle 12 and the second baffle 13 to displace until the first ventilation slot 5 and the second ventilation slot 6 are completely blocked. The other end of the first wire body 31 is provided with a winding drum 35 and is fixedly connected thereto. The outer wall of the winding drum 35 is fixedly connected to the other end of the second wire body 32. The winding drum 35 is located on the outer wall of the connecting shaft 21. A limiting strip 36 is provided between the connecting shaft 21 and the winding drum 35. The limiting strip 36 can slide freely between the connecting shaft 21 and the winding drum 35. The end of the limiting strip 36 is provided with a bent rod 37. The bent rod 37 is Z-shaped and the bottom end portion is cylindrical. The bent rod 37 slides freely on a part of the side wall of the winding drum 35. One side of the end of the bent rod 37 is provided with a magnet 38. The magnet 38 is located on the inner wall of the winding drum 35 and is fixedly connected thereto. The end of the bent rod 37 has magnetism that attracts the magnet 38. One side of the winding drum 35 is provided with a fixing plate 39. The bottom of the fixing plate 39 is fixedly connected to the integrated element 2. An electromagnet 40 is provided above the fixing plate 39 and is fixedly connected thereto. When the electromagnet 40 is energized, the magnetic force generated is greater than the magnetic force generated by the magnet 38. When the bottom end portion of the bent rod 37 is adsorbed on the surface of the electromagnet 40, the limiting strip 36 slides downward until it completely disengages from the connecting shaft 21. The electromagnet 40 is electrically connected to the motor 20;

[0044] During use, when the motor 20 is started, the limiting strip 36 is located between the connecting shaft 21 and the winding drum 35 at the same time. Therefore, the winding drum 35 will drive the first wire body 31 and the second wire body 32 to wind around the surface of the winding drum 35 in a state of self-rotation, thereby driving the first baffle 12 and the second baffle 13 to translate in opposite directions simultaneously by the first wire body 31 and the second wire body 32, and finally exposing the first ventilation slot 5 and the second ventilation slot 6 to the air. At this time, the motor 20 will pause after rotating to a preset number of turns. The electromagnet 40 will be self-energized. The magnetic force generated will cause the bent rod 37 to disengage from the magnet 38 and drive the bottom cylindrical area of the bent rod 37 to insert into the inside of the fixing plate 39. At the same time, the upper end portion of the bent rod 37 will also be pulled out from the inside of the winding drum 35, allowing the limiting strip 36 to automatically fall into the inside of the winding drum 35 due to its own weight and completely disengage from the connecting shaft 21. In this state, the bent rod 37 limits the rotation of the winding drum 35, keeping the winding drum 35 and the first baffle 12 and the second baffle 13 at the ends of the first wire body 31 and the second wire body 32 in an open state;

[0045] After that, the motor 20 will start again, and the fan will function through the transmission effect in the above-mentioned cooling unit 11, and suck in a part of the air body from the second air box 30 into the gap between the fins 4 and the inside of the entire housing 1, and finally discharge it outward from the second ventilation slot 6. The area through which the air body passes covers the entire integrated component 2 inside the housing 1, greatly improving the heat dissipation and cooling effect, ensuring that the inside of the gateway is protected at an appropriate temperature, and reducing the occurrence of potential problems; after the temperature sensor 41 detects that the temperature is stable, it can drive the rotation shaft of the motor 20 to reset, so that the electromagnet 40 loses the power-on effect, and the attraction of the magnet 38 will automatically drive the end of the bending rod 37 to push into the inside of the winding drum 35. Under the action of the bottom inclined surface of the limiting strip 36, the bending rod 37 will return to its original position again, and connect the connecting shaft 21 and the winding drum 35 again.

[0046] According to the above embodiment, Embodiment Three,

[0047] The inner wall of the bottom box 7 is provided with an arc-shaped strip 15. The inside of both the bottom box 7 and the upper box 8 is provided with a sliding groove 16 for the arc-shaped strip 15 to slide. The arc-shaped strip 15 includes a bent portion 17 and an arc surface portion 18. A cotton strip 19 is provided on one side of the arc-shaped strip 15 and is fixedly connected thereto. The side surface of the cotton strip 19 is in contact with the outer wall of the power cord.

[0048] The end of the air outlet pipe 9 is shaped like an arc. The air body discharged through the air outlet pipe 9 acts on the junction of the bent portion 17 and the arc portion of the arc-shaped strip 15, thereby driving the arc-shaped strip 15 to rotate continuously between the bottom box 7 and the upper box 8. On the one hand, the rotating arc-shaped strip 15 can disperse the air body in the area where the arc-shaped strip 15 does not rotate. The area covered by the dispersed air body keeps changing in real time, and at the same time spreads backward along the wiring route of the power cord, so that all areas of the outer wall of the power cord are well cooled; on the other hand, the rotating arc-shaped strip 15 can also drive the cotton strip 19 on one side of it to rotate, and the cotton strip 19 will automatically wipe the dust attached to the outer wall of the power cord appropriately, so that this area remains clean during long-term use, reducing the entry of dust into the connection area of the circuit and reducing the occurrence of potential problems.

[0049] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0050] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
